Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31204, here are decompositions:

  • 11 + 31193 = 31204
  • 23 + 31181 = 31204
  • 53 + 31151 = 31204
  • 83 + 31121 = 31204
  • 113 + 31091 = 31204
  • 191 + 31013 = 31204
  • 227 + 30977 = 31204
  • 233 + 30971 = 31204

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 31204 first appears in π at position 235,843 of the decimal expansion (the 235,843ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
